Applicatinn filed May 19, 1919. Serial no. 298,153.

To all whom it may concern:

Be it known that I, LEMUEL O. ANDnRsoN, a citizen of the United States,residing at Miami, in the county of Dade and State of Florida, haveinvented a new and useful Sash-Fastener, of which the following is aspecification.

The present invention relates to window sash fasteners and has as itsprincipal object to provide a window sash fastener which will retain thesash in any adjusted raised position and which will obviate rattlingorvibration of the sash with respect to the w1ndow frame.

A second object of the invention is to provide a sashfastener of thistype which will positively retain the window in raised position and, atthe same time, dispense with pulleys, weights, et cetera, that arecommonly used.

Another object of the invention is to provide a sash fastener which isdurable and which can be used in connection with any window sashconstruction without necessitating the defacing of either the sash orthe window frame.

Another general object of the invention is to provide a window fastenerhaving the above characteristics which is simple in construction, whichconsists of few parts, and which may be manufactured and placed on themarket at a minimum cost.

With the above and other objects and advantages in mindthe inventionconsists of combinations of elements, constructions and arrangements,operations and general assemblage, the details of which will behereinafter set forth inthe appended claim, one embodiment of theinvention being illustrated in the accompanying drawings, wherein Figurel is a view partly n section and partly in elevation showing a windowconstruction having my improved fastener 'associated therewith; r

Fig. 2 is a fragmentary sectional view of one of the side rails of thesash and the adjacent part of the sash frame showing my improvedfastener applied thereto, the fastener being shown in longitudinal crosssection; and

Fig. 3 is an elevation taken on line 3-3 of Fig. 2. L

Referring to the drawing, wherein like characters of reference designatelike parts on all of the views, the numeral 5designates a verticallymovable sash while 6 designates one of the side rails of the windowframe having a recess 7 extending transversely therethrough and openingupon. its

face which is opposed to the inner longitu=- dinal face ofthe windowsash.

My improved fastening device comprises a cylinder or barrel 8 open atboth ends which is seated in the recess 7. Formed on the inner end ofthe cylinder or barrel and de-' tachably conect'ed therewith is theplate 9 which is secured to'the' window frame by.

fastenings 110 Longitudinally movable in the barrel or cylinder 8 is aplunger or head 11 which is formed with forwardly projecting bearingarms 12 between whlch is mounted a rotatable roller 13 having itsperiphery formed I with ribs or corrugations 14. A corrugated or toothedplate 15 is secured to the window sash and extends longitudinallythereof and is adapted to be traversed by the roller 13 during thelowering and raising of the sash.

The roller 13 is adapted to frictionally engage the sash and retain thesame in raised position. In orderv to retain or project'the roller intoengagement with the corrugated plate an expansible coil spring 16 isprothe cylinder or barrel 8'.

It will be manifest that the eXpansible spring will force the rolleragainst the corrugated plate of the sash into a position as to retainthe'sash in any raised position, the teethor corrugations on both thewheel and plate aiding the spring in this function, and that the sashwill at all times be held against vibration.

The embodiment of the invention herein shown and described is consideredthe preferred construction, but it will be understood that the same maybe modified in many respects, and that my limits of such modificationare governed only by what is claimed.

What is claimed is A sash fastener comprising a face plate having meansof anchoring the same and having a central slot, a tubular casinghavingv both ends open and having one end provided with outturnedapertured ears detachably connected. to the'plate, saidcasing'having itsinner end bent inwardly to form a. shoulder, an apertured disk abuttingsaid shoulder, a

hollow tubular plunger snugly fitting Within the casing having an innerend Wall and open at its outer end, said plungerhaving integral bearingsextending from the edge thereof at diametrically opposite points, aroller journaled therein and projecting through the slot and anexpansible spring in the casing between the end Wall of the plunger andthe disk and tending to force the roller to a projecting position.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two Witnesses.
